China DOS Union

In the mechanical engineering department computer lab, the language used most is FORTRAN. But FORTRAN can really be too annoying sometimes. When there are too many compile errors, you can hardly even see them clearly. What to do?
When compiling, the compiler will ask you:
Microsoft FORTRAN77 V3.13 8/05/83
Object filename :
Source listing :
Object listing :
Usually everyone just presses Enter to ignore it, but actually at
Source listing :
on that line you should give an LST filename, such as A.LST. Open this file and you can see the following:
1. FORTRAN version information
2. Source listing
line number statement
*****error information
3. Variable information
4. Summary
This way, you can clearly see the error location and type, which makes it convenient to check, and then
fix it in the source program.
An example is attached below:
A.LST file:

Fortran77 is not as good as Basica

fortran77 is a powerful engineering calculation language. Its calculation precision is far beyond what basic can match...

fortran has no real practical use; in most cases it's only used for teaching.
